EES (pronounced 'ease') is a general equation-solving program that can numerically solve thousands of coupled non-linear algebraic equations. The program can also be used to solve differential and integral equations, do optimization, provide uncertainty analyses, perform linear and non-linear regression, convert units, check unit consistency, and generate publication-quality plots. A major feature of EES is the high accuracy thermodynamic and transport property database that is provided for hundreds of substances in a manner that allows it to be used with the equation solving capability.The EES (Academic License) is no longer available for installation on a personal computer.





EES is no longer allowed to be run on personal computers, and existing EES licenses have been expired. 
EES can be run on any University of Illinois-owned computer in the Department of Mechanical Science and Engineering, but the software must be installed by Engineering IT.  Access to the installation files is restricted to IT personnel only.  If you need EES installed on a University-owned computer, please email

EES is available on-campus in the Engineering Workstation Labs in the Mechanical Engineering Lab (MEL).
